tamsin I had a similar experience when I applied for ESA.
I found the whole process humiliating, degrading and full of flaws.
I was placed in the support group with 51 points and after I complained they placed me in the support group.
I'm having a similar experience now trying to get my nhs IHR because the doctors they use are ATOS and no matter how much medical evidence I submit, they don't assess it properly and consequently I've been turned down twice so far but I'm still battling on with the assistance of my union.
I lost my job last year due to ill health.
